Be it known that l, FRANK Ill 125K ER, of St. Louis, i\lisso uri, :avemade a new and useful Improvement in Sheet-Metal Ceilings, \Valls, orlianels, of which the following is a lull, clear, and exact description.L r

In the annexed drawings, making part of this specification, Figure l isa view, from beneath,ofa ceiling in which the improvementin to questionis embodied. One only ofthe panels or sheets shown corrugated. Fig.2isavertical section, upon an enlarged scale,on the line 2 2 of Fig. 1.Fig. 3 is a vertical section, enlarged, on the line 3 3 of Fig. 1. Fig.4 is a I 5 vertical section, upon a still larger seale, showing aportion of Fig; 2; and Fig. Sis aviewih perspective, from beneath, ot'aportionof the improved ceiling, portions being broken away -to exhibitthe interior construction; 1 The same letters of reference denote thesame parts. I The ceiling is composed substantially of the sheets A. andthe parts styled the cross- At one of its side edges the sheet 5. isinclined upward to form a flange, u; Figs. 2, 4, and the flange ispreferably extended, at a, backward above the main portion of the sheet,substantially as is shown. At its opposite'sidc edge the sheet is turnedbackward upon itself, and also upward, substantially as isshown at'a'antl i'rom'the-uppermost point of the part tr the sheet is extendedhorizontally outward, substantially as is shown at a. The sheet is alsopreferably shaped to form .5 what may be st-ylcd the longitudinal bar,Cthat is, the sheet is bent downward ate and then upward at ci1 nd thusa rib or bar of any desired depth may be introduced into the sheet inthe immediate vicinity of the fold 4 aa; and while I desire not to belimited to the precise form in cross-section shown of the" bar G, Iconsider it a desirablcone as well for.

its appearance as on account of its being a desirable mode ofstrengthening that edge of the sheet and of supporting the adjoiningsheet, the several sheets forming the ceiling being combined aslollows':Beginning at theside of the room, the flange a of the first sheetismatle to rest upog a suitable support, such as the molding I), ,lgs.1, 2. For this purpose the molding is cut away at d to receive the edgeof dog fold, and the edge of' the adjoining sheet the fold 16- a.

the sheet, substantially as shown in Fig. 2. I desire not to be confinedto the particular manner shown of folding the sheet to forin the flangea, provided the construction is such as to permit of that part of thesheet to be received into a supportingfold, such as the fold a a of theadjoining sheet, as shown in Figs. 2, eL-that is, the fold a a must be arc-eutcrmust be adapted to enter and be held within The improvementtherefore can, in a measure, be carried out by entirely oniitting'theflange a and by correspondingly shaping the fold a c to admit andsupport the unlianged adjoining-sneetrd prefer," however, the particularshape shown'in all respect's, as thereby the improvement is best carriedout. The outer edge of the sheet A, Fig. 2, is secured to the joist E,or otherfire ture of the floor to which this ceiling is being applied,by means of nails F or other equiva lent fastenings passed through thepart a upward into the joist, substantially as is shown in Fig. 2. Theedge of the adjoining sheet,

. A, Fig. 2, is thcirpassed into the fold a" of, so

as to rest therein, and so as to conceal the nails F, and then the outeredge of that sheet A in turn is niadeto support the rear edge of thenext sheet, and so on throughout the width of the ceiling. Thecross-bars B are used at the 4 ends of the sheets A. Their principalfunction is to complete the design of and give a finish to the ceilingat that point; but they also serve a useful purpose in stiffening thesheets at their ends. To this e'nd that portion of the cross-bar'whichappears-to view may he made to conform to the appearance of the bar C;hence inv this respect the cross-bar may be of various shapes. Itisattached in 0 position by means of its-folds b 1), into which the ends aai'rcspectively, of the adjoining sheets are respectively received,substantially as is-showu in Fig. The cross-bar extends across the widthof the sheet, and at its endsabuts upon the longitudinal bar 0. Arosette,- G, Fig. 1, .or other ornamental piece, may be used tocover thebars B G where they come together, and itmay be secured in place 'by anysuitable fastening. sheet metal is liable to sag or to warp out ofshape, and to prevent this, as well as to fur- A plain panel of .100

ther improve the design of the ceiling, a corrugation, a", Figs. 1, 3,5, is introduced into the sheets A. The corrugation is crosswise in thesheet, and it is better to extend it throughout the width of theoriginal sheet, so that when the bar 0 is subsequently formed in thesheet the corrugation extends into the bar, substantially as isindicated in Fig. 5.

Although the corrugation a? is crosswise in the sheet, I desire not tobe restricted thereto, as it may extend longitudinally in the sheet. Itis better, however, to extend the corrugation in the manner shown. It isalso preferable to have the rib 0 formed in the sheet as one partthereof; but, if desired, the rib may be in the form of a separate pieceand be at tached to the sheet A.
